TYPEJHRITING MACHINE.

Original application and February 12,

Be it'known that I, LESLIE HAROLD-FRIED- MAN, asubject of the King of Great. Britain and Ireland, previously residing at 268 in the post town of East bourne, but now a] resident of Killeen.

Grey street, in the city of St. Kilda, a suburb of the cit-y of Melbourne, both in the county of Bourke, State of Victoria, Commonwealth of Australia, have invented certain new and useful Improvements in Type- IVrit-ing Machines.

in the Specification of my prior United of which the following is aspeclfication.

.This invention relates particularly .to typewriting machines of the kind described States PatentNo. -.-1056657 issued March 18th, 1913, wherein the carriage is auto matically returned at the end of each line written. Y

The main object oi the present invention is'to provide for the paper roller of the machine being" partially turned and for the returningmechanism. being operated from the keyboard of the machine, when desired, before a line has been completely written and also to partially turn the paper roller with each such 1 premature operation of the returning mechanism. Thearrangement in this invention is such that the paper roller may not only be operated with each.

automatic return of the carriage and with each premature operation of the returning mechanism but may also be partially rotated, without in any way operating the carf'riage returning mechanism and quite regardless of the position of the carriage.

-'Other objects and advantageswillbe in part apparentand in part pointed out here- I, after.

Referring'to the drawings which form a part of this specification Figure l -is a view showing mechanism by which the paper roller may be partially turned by the depression of a key. Fig. 21s a view of one end of the carriage showing the relationsgship between various parts for turnin: the

its upper end, to the rear the left hand end of the traineworln At its lower end lllB C-ltltCll lever 113 is provided with adjusting screws 115 which engage with the slide 112 and'with the framework. of the machine. Adjoining (Fig. 5) the slide 112 is also an outer clutch lever 116. This is pivoted. by a pivot pin 117, at its upper end, to the rear of the left hand end of the irai'nework. The outer clutch lever is provided at its lower end with adjusting screws 118. Extending between the clutch levers 113 and 116 is a contracting spring 119.

Between (Fig. 5) the clutch levers is a driving drum. 1.11, having inner teeth 121 and outer teeth 122. \Vithin the driving drum is a. coiled ribbon tension spring 123.

The drum 126 is loosely mount on the axle 124. Secured (Fig. 4). to the circumference of the innerclutch drmn 126 1s a winding'end 130 of a first tape 131. The other or carriage end 132 of th'esaid first tape is"secured to the ri lit hand end of the carriage 5. Between ig. 5) the driving drum 120 and the outer clutch lever 116 is an outer clutch drum 133 having teeth 134:. The drum 133 is loosely mounted ,on the axle 121-. Secured (Fig. 4.) to the circumference of the. said drum 133 is the winding end 135 of a second tape 136. The other or cam end 137 of the said tape 136 is secured to the circumference of aeam 138. The cam 138 is mounted upon the outer end of a spindle 139 mounted u ion the inner en of which is a wheel 140.- eeured to the circumference of the wheel 140 is the winding end 141 of a third tape 142. The other or carriage end 1-113 of the third tape 142 is secured to the left hand end of the carriage 5.

Pivoted to the rear of the framework is (Fig. 7) a key lever 17'? having a key 178. Attached tothe said key lever 17? is one end of-aspring 179 the other end of which isottached to the key lever 64:. Depending from the lever 177 are lugs 180 carrying a pivot pin 1S1 to wh'ch is pivoted the said key lever 61. Pivoted (Fig. 6) by a pivot pin 182 to the key lever 17? are the lower ends of two links 183. Pivoted by a pivot pin 18% to the upper ends of the links 183 isthe' front end of a lever 185. Secured to the rear end of the lever 185 is a cross spindle 186 projecting from which is a lever 18?. Pivoted by a pivot pinlSS to the lever 18.? is the lower end of a connecting: rod 189. livoted (by a stud 190) to the framework of the machine is a lever 191 having an upper arm 192. Projecting from the upper arm 192 is a finger 193. This engages the reversing bar 86 as will be hereinafter understood .The said lever 191 is also provided with a lower arm 191." The lever is pivoted by its lower arm 191 to the stud 190. Pivoted to the said lever by a pivot pin 195 is the upper end of the connecting rod 189.

,The cycle of operations with this invention is as follows :--l pon each depression o-f'a key 6 or its equivalent it will be oh\ ions that the escapemcnt mechanism at'crr-lescribed permits the carriage 3 to more a certain distance from right to left as in an ordinary typewritingr machine. The inner clutch drum 126 is new in engagement with the driving drum 120 which is rolalod y its tension spring 123. The inner clutch drum 126 is therefore being driven by the driving .drum 12m ns direction oftrayel being indicated by the arrows shown in Fig.4.. The drum 126 draws -with.-it,.each time akey is depressed and it-is permitted to travel, the

winding end 130' accountof thecarriage end 132 of this tape,

of the first tape 131. a On being attached to the right hand end or the carriage the said carriage moves in the direction indicated,- 2'. e. from right to left. Upon. the carriage 5 reaching the end of a.

,line the pivoted clutch levers 113 and 116 are operated in the manner described in my prior United States Patent No. 1056657 which throws the inner clutch drum 126 out of engagement and ,the outer clutch drum 133 into engagement.- .with the driving drum 141 of the-third tape 142.

120. Immediately this occurs the tension spring 123 within the driving drum 120 drives the outer clutch drum 133 which, by the second tape 136 moves the ca'm 138 in the opposite direction to that indicated by :tac'hed to the left hand end of the carriage .5 the said carriage moves in a reverse directio'n. to that whichit previously traversed from left to right, and thus the said carriage is returned to the position it first occupied.

Should it be desired to return 'or' reverse the carriage before the end of a line is reached such may be accomplished by depressing the key 17 8 thereby depressing also the key lever 177 by which it is carried.

This operates, by the links 183 and leverdrum 120.

185, the cross spindle 186 to which is at tached the lever 187. The connecting rod 189 is thereby forced upwardly operating the lever 191,'the finger 193 of the upper arm 192 of which is thus brought into engfi ement with the reversing bar'86. This action mo'ves the reversing bar 88 from right to left operating the clutch levers 113 and 116 by mechanism disclosed by prior Patent No. 1056657 as before mentioned and thereby throwing the inner clutch. drum 126 out of engagement and the outer clutch drum 133 into engagement with the driving The carriage then travels to ward its original position as already set forth. 'It is. necessary for the typist to retain the key 178 depressed for as long as it is desired'for the carriage to return. immediately. the finger is removed from the key 178 by'rnechanism disclosed by the prior Patent No. 105665? the reversing bar 86 returns 'to its original position and disengages the outer clutch drum 133 and once more engages the inner clutch drum 126 with the driving drum 120." As the carriage returns from the end ofa line it will be plain; that the roller 43 upon the tripscribed crank lever which by per' ll engages with the pathway 51 of the deflector 49.. This operates the afor'edeg its upper arm 37 operates the link 35 throwingthe pawl 32 into engagement with the rate et ring 23 at the end of the roller 22. 2-2 is thus turned automatically as the carriage returns. Upon, the carriage "mov ing normally, that is from right to left it will be seen that the tripper iii/being pivoted to .movein one directiononly' 91igages with the pathway 50 of the defi'ece tor 19 and turns or pivots upon the pivot pin 35% The crank lever therefore, does not operate'when the carriage 5 isso' moving and the roller 22 is notthen turned.

Should it he dosired'to turn the paper roller before the end ofa'line is reached the key 65 is depressed drawing downwardly the connecting rod 62. By the fluted roller 59 and toothed sector 58', the spindle 5'Zand 1 lever now operate the link 52. This enwith the upper arm 37 of the crank lever which operates the link'35 and ratchet ring 23 as described. "When the key 65 is depressed the spring 179 returns the said key; but the said spring is not strong enough to draw. downwardly with it the.

key lever 177. When the key'178 and lever 17'? are depressed the lever 64 being heneath them is'depressed also. The carriage 5 is therefore not onlyreturned as before described but the roller 22 is'also rotated in th manner which has just been described. lVhen the carriage 5 is returning under any circumstancesthe toothed sector 58 carried by the carriage slides-along the fluted roller 59 carried by the framework 2.

Upon the carriage being returned before it has reached the end of a line it is obvious that the paper cannot be automatically turned by the tripper 11 and deflector 49 as the link 52 will be in engagement as described, with the upper arm 3701 the trippers crank lever, the lower arm 40 of which will consequently have lifted or ele 'atedthe tripperclear'of the deflector 19.

Should itbe desired to turn the paper by The rollerhand the finger catchdS of the hand rod 1-7 may be moved and by thelever es and link operate the crank lei-'er,link.35,and pawl 32 as aforedescrioeol.
